ServiceLevelIndicators

NuGet Package

A .NET library for emitting Service Level Indicator (SLI) latency metrics via the standard System.Diagnostics.Metrics API. Use it to measure operation duration across any .NET application — console apps, background services, worker processes, and more.

For ASP.NET Core applications, see ServiceLevelIndicators.Asp.

Installation

dotnet add package ServiceLevelIndicators

Quick Start

1. Register with OpenTelemetry

builder.Services.AddOpenTelemetry()
    .WithMetrics(metrics =>
    {
        metrics.AddServiceLevelIndicatorInstrumentation();
        metrics.AddOtlpExporter();
    });

2. Configure options

builder.Services.AddServiceLevelIndicator(options =>
{
    options.LocationId = ServiceLevelIndicator.CreateLocationId("public", "westus3");
    options.CustomerResourceId = "my-customer";
});

3. Measure operations

Wrap any block of code in a using StartMeasuring scope:

async Task DoWork(ServiceLevelIndicator sli)
{
    using var op = sli.StartMeasuring("ProcessOrder");
    // Do work...
    op.SetActivityStatusCode(ActivityStatusCode.Ok);
}

You can also pass custom attributes:

var attribute = new KeyValuePair<string, object?>("Event", "OrderCreated");
using var op = sli.StartMeasuring("ProcessOrder", attribute);

Emitted Metrics

A meter named ServiceLevelIndicator with instrument operation.duration (milliseconds) is emitted with the following attributes:

Attribute Description
Operation The name of the measured operation
CustomerResourceId Identifies the customer, customer group, or calling service
LocationId Where the service is running (e.g. ms-loc://az/public/westus3)
activity.status.code Ok, Error, or Unset based on the operation outcome

Key APIs

Type / Method Description
ServiceLevelIndicator.StartMeasuring(operation, attributes) Start a measured operation scope
MeasuredOperation.SetActivityStatusCode(code) Set the outcome status
MeasuredOperation.AddAttribute(name, value) Add a custom metric attribute
MeasuredOperation.CustomerResourceId Get/set the customer resource ID
ServiceLevelIndicator.CreateLocationId(cloud, region?, zone?) Helper to build a location ID string
ServiceLevelIndicator.CreateCustomerResourceId(guid) Helper to build a customer resource ID from a service tree GUID
